I'm currently doing my PhD in Canada, and here, spouses of the above categories automatically get open work permits for as long as the student/work permit of the principal applicant. Heading towards the job market, there are lot's of opportunities in the US, both within academia and industry, but the fact that my wife would not be able to work is a huge deterrent for us. Add to that, my wife is not in an industry where she would be likely to get a company sponsoring her for an independent work permit.
